Application filed January 31, 1916. Serial No. 75,426.

To all whom it may concern:

I Be it known that I, HORACE B. KING, a citizen of .the United States,residing in Boerne, in the county of Kendall andState of Texas, haveinvented certain new and useful Improvements in Oil-Tank Gages, of

which the following is a specification.

This invention relates to gages for measuring the depth of oil in tanksand otherreceptacles. The gage ordinarily 'used for this purposecomprlses a pole having a suitable scale marked on-it and to measure thedepth of oil in a tank or other receptacle with such gage the pole islowered until it touches the bottom of the tank. The part of the polewhich enters the oil will of course have oil deposited on it and theupper edge of this oiled portion of the pole indicates the depthof theoil in the tank. It

has been'thwpractice to insert a pin at the upper edge of theoiledportion of the pole and then test the accuracy of the measure-- .ment bylowering the .pole until it touches thebotto n of the tank and then ifthe pin just touches .thesurface of the oil it will be understood thatthe measurement is accurate; if not, the pole must be raised and the pininserted at another point and again tested. .It is quite common toinsert the pole in the oil and take it out for mspection several timesbefore the correct adjustment can be made and the exact depth of the oilfound.

. According to my invention I provide a gage-comprising a pole to whichis secured a scale plate and on which is mounted two slides, the lowerone of which carries a needle-or pointer and the upper one .of which.carries a set screw. The .needle- .carrying slide is adapted to move onthe lower portion of the pole and it is connected to'the upper slide byrods in such manner that by moving the upper slide vertically on thepole the'lower slide. may be corresponidingly moved and thus when theneedle is made'to rest on .or touch the surface of theoil the upperslide may be made fast to the gage-pole and the-depth of the oil may beaccurately determined. which is usuallymade of wood, is preferablyprovidedat' its lower end with a weight which causes it to sink andprevents it' from rising when lowered.

In the accompanying drawings, Figure -1 is a view in elevation, and withparts broken away, of a well known form of oil tankandb, as shown inFig. 4, and the downward' The gage pole it illustrates how my inventionis i applied thereto; Fig. 2 is a perspective view of my Improved 011tank gage with parts of the gage-polebroken away. Fig. 3 shows a;

transverse sectien on .the line 3-3-of Fig. 2.

Fig. 4 shows an elevation of the lower por-' tlon of the gage-pole withparts in section and illustrates how the weight is" applied thereto.

The tank A is provided with an opening a which may be closed by a screwcap or in any other suitable way; -When it is de-' sired to measure. thedepth of oil in the ank the gage-pole B is inserted and is held by theattendant who may stand on a platform C. The pole B is preferably madeof wood having attached to its lower end a weight-b which causes. it tosink and stand erect in the oil and prevents it from rising therein.

D indicates a Scale plate which is attached to one side of the pole. Itserves to prevent the wood from warping or bending and ,it is suitablygraduated as indicated.

E indicates the lowerslide in the form of a'collar surrounding thelowerportion of the pole and carrying the needle or pointer F. l

G indicates a similar slide surrounding the upper portion of the poleand carrying aset screw H.

The slides E and G are connected by Vertical rods 6 and the arrangementis such thatby moving the up er slide vertically on the pole the lowernee le-carrying slide may be correspondingly 'moved. The pole may be ofany desired length and the collars E and- G may beheldany suitabledistanceapart by the rods e. Preferably, however, the dimenslons aresuch that the-collar G shall be always outside thetank or very close to.

the topthereof so that the attendant may easily grasp it and move-it upand down on the pole. In this way when the pole is insertedit may bereadily made to rest on the bottom of-the tank, asindicated in Fig- 1.By manipulating the slide G and'watching the needle F, the latterflmaybe made to touch the surface of the oil, then the collar G maybe madefast to the pole by the setscrew H and the exact depth of oil may beread .on the scale. When the depth of oil is known the number of gallonsof oil in the tank may be ascertained from suitable.

tablesprepared "for that purpose. The

scale D extends to the bottom of the vweight movement of the lower slideE may be limited by lugs 72 on the weight which preferably permits theslide to move downward to within of an inch of the bottom of the tank.

As before stated, the exact dimensions of the pole D are not essential,but in practice I have used a pole 18 ft. long so that when applied to atank 10 ft. in diameter the outer end of the pole will extend 8 ft.above the top of the tank. In such case the rods 6 should be about '8ft. long, thus holding the slides E and G 8 ft. apart.

I claim as my invention:

1. An oil tank gage, comprising a gage pole, a needle-carrying slidemounted to move on the lower portion thereof, a needle projectinghorizontally from the slide, means extending to the upper portion of thepole for raising and lowering said needlecarrying slide, and devices forsecuring said means to the upper end of the pole when theneedle-carrying slide is adjusted.

2. An oil tank gage, comprising a gagepole weighted at its lower end, aneedlecarrying slide on the pole and another slide on the upper portionof the pole, a needle projecting horizontally from the slide, providedwith means for making it fast to the .pole and which is connected withthe needlecarrying slide.

3. An oil tank gage, comprising a gagepole, a needle-carrying slidemounted to f move on the lower portion thereof, a needle projectinghorizontally from the slide, an-

other slide mounted to move on the upper portionof the pole, rodsconnecting the two slides and a set-screw carried by the upper slide.

4.. An oil tank gage, comprising-a wooden pole, a weight attached to thelower end of the pole a plate secured to one side of the pole an whichis provided. with a suitable .scale, a needle-carrying slide mounted toislimited by said lugs, and means extending to the upper portion of thepole for raising and lowering said needle-carrying slide.

6. The combination with a tank having an opening in its top, of a gagecomprising a gage pole adapted to enter the opening in the tank and torest on the bottom of the tank, a needle-carrying slide mounted to moveon that portion of the pole within the tank, a needle projectinglaterally from the slide,.means extending to the upper portion of thepole above the tank for raising and lowering said needle-carrying slide,and devices for securing said means to the upper end of the pole whenthe needle-carrying slide is adjusted.

In testimony whereof, I have hereunto subscribed my name.

HORACE B. KING.
